How can I tell if my engine has a 1-piece or a 2-piece rear main oil-seal without removing the oil pan? The engine is on a stand and access to the flex plate is easy. I can see an aluminium plate bolted to the rear of the block behind the flexplate. Is this of any help? The reason I need to know this is that I want a cast aluminium pan for this engine. Which brings me to my next question! Anybody know where I can get one of these pans?
Thanks.

 

sounds like you have a one piece seal

I have the 1986 shop manual:

The oil pan gaskets are one piece for all V8 engines in 1986.
